The Ping G15 Irons Steel 3-9PS is in my friend's bag

Ping G15 Irons feature a wide sole which enables them to sit comfortably behind the ball and a large offset which positions the hands forwards. This provides those who may have trouble getting the ball airborne with a confident feeling that this can be achieved and this indeed proved to be the case.
The technology of the G15 Iron provides the high-launching, maximum forgiveness benefits that the majority of golfers rely on to bring consistency to their iron play. The stainless steel iron’s cavity design features a new Custom Tuning Port (CTP) which expands the perimeter weighting and increases the moment of inertia. Weight savings from a thinner face is re-positioned to the toe for added forgiveness on mis-hits and its wider sole produces a higher launch angle. Stronger lofts combine with a center of gravity located low and farther from the face to produce longer shots without sacrificing the higher trajectory required in a maximum forgiveness iron.
